Oil-free silent air compressor, as the name suggests, is an air compressor designed to do not need to use lubricating oil during operation. This type of air compressor usually uses special design and materials to reduce the friction and wear between mechanical parts, so as to achieve oil-free operation.
The water-lubricated oil-free variable frequency screw air compressor of Shanghai Grankering Group is such a device. It uses water lubrication technology, through water to replace the traditional lubricating oil, to achieve the oil-free compression. This design not only avoids the risk of oil contamination, but also provides more pure compressed air.
Question: Since it is an oil-free air compressor, does it not need to add any lubricant at all in daily use?
Answer: Yes, the oil-free silent air compressor does not need to add any lubricant during normal operation. Its design concept is to reduce maintenance costs and avoid oil pollution through oil-free technology. It should be noted, however, that while the oil-free compressor itself does not require refueling, other auxiliary systems (such as certain types of bearings or seals) may still require a small amount of lubrication or cooling. In these cases, a lubrication system completely isolated from the compressed air is usually used. However, for the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, due to its use of water lubrication technology, even these small amounts of lubrication requirements have been replaced by water. Therefore, in daily use, users do not need to worry about adding lubricant.
The standard of exhaust oil content of screw air compressor is usually measured by the number of milligrams of oil per cubic meter of compressed air (mg/m & sup3;). Different applications and industries have different requirements for the quality of compressed air, so there will be different oil content standards.
Hospital air compressors play a vital role in the medical field. It is one of the main components of the medical air system and is specifically designed to meet the various needs of the hospital's specific environment. The following is a rigorous description of the hospital air compressor: 1. definition and type of hospital air pressure
The requirements of the food industry for air compressors mainly include the following: High air quality requirements: It is necessary to keep the air clean during food processing to avoid pollution. Therefore, the air compressor must have an excellent filtration system and air purification function to ensure that the output pressure
The pressure range of compressed air commonly used in factories is usually 0.5 MPa to 1.0 MPa(5 bar to 10 bar). The specific value needs to be determined comprehensively according to the process requirements, equipment type and industry specifications. The following is a detailed analysis: 1. the pressure range of conventional application scenarios
When selecting a compressor based on gas consumption, the following key factors need to be considered: Determine gas consumption: First, accurately calculate or estimate gas consumption, which includes the use of compressed air, the use of the process and the future development of space. The calculation of gas consumption shall be based on the equipment's
The pressure of the plant gas supply usually depends on the specific application needs and equipment specifications. Generally speaking, the air source pressure for industrial use is usually between 0.6MPa and 1.0MPa, which is a relatively general range and is suitable for most pneumatic tools, automation equipment and other
Among the many air compressor brands, which one to choose has become a problem faced by many users. If you are looking for an efficient, environmentally friendly and high-quality air compressor, the water-lubricated air compressor produced by Shanghai Granklin Group is undoubtedly your wise choice. granklin, shanghai
The power frequency air compressor and the permanent magnet air compressor are two different types of air compressors, each of which has its own characteristics and applicable scenes. The following will compare and summarize these two air compressors from many aspects. 1. working principle of power frequency air compressor: driven by motor
The air compressor is not an electronic device, but a general-purpose device. It is a device that uses an electric motor or other power equipment to drive, compress and store air. Although the air compressor may contain some electronic components, such as sensors and control systems
Oil-free piston air compressor has a variety of uses, including: as a power source: compressed gas can be used as power, used to drive a variety of pneumatic machinery and pneumatic tools, as well as control instruments and automation devices. For refrigeration and gas separation: gas through pressure
